This invention-relates to certain novel improvements in boot and shoeconstructions and has for its principal object theprovision of animproved construction of this character'which will be eflective in useand economical in manufacture.

= The salient object of my invention is to provide an improved means forattaching the sole and heel in position in boot and shoe '1constructions. I j

1 Another object of the invention, ancillary to the foregoing, is toprovide a construction of the above'named char'acter which will bearrangedsuch that the sole and heel may be 'ex peditiously removed whenso desired.

7 Other objects will appear hereinafter.

, The'invention consists in the novel combination .and arrangement of.parts to behereinafter described and claimed.

Fig. 12. is an-elevatiolial detail view ofa The invention will be bestunderstood by modified form of construction for the device depictedbestin Figs. 5 and 6. V

I In the-accompanying drawing wherein I have illustrated the preferredform of construction for my devicelO indicates the outer sole of myimproved construction and 11 indicates the outer ply of'the heelconstruction and this sole and outer ply are preferably formed from agood grade of material as is well understoodrin the art, it being understood that myinvention is adaptable for use in connection with any typeof material; as

for example, leather, rubber, or so-oalled com position material.

In the drawing 12in dicates theusualiir termediatev sole employed inboot and shoe construction and 13' indicates the usual insole. Theforegoing portions are ordinary in shoe construction and theformation-there of and the materials from whichthey might best be madeis well understood in the art.

In the insole l3 I provide adjacent the edges thereof in spaced apartrelation a plus rality of openings 14: which are preferably arranged inthe disposition best depicted in Fig. 3 although it is to beunderstoodthat analogous arrangements might be made without departingfrom the purview ofumy invention. On the intermediate sole 12 I secure aplurality of so calledanchoring elements 15' which, as clearly depictedin Fig.-11, have pointed projections 16 extending-there.- from and whenthe device is assembled these projections 16 are preferably arranged atright angles to the main body of the mem bers l5 and are inserted intothe intermediate sole 12 on the side thereof intended to be directedtoward the insole 13. At substan I tially the midpoint of the main bodyportion of the anchoring elements15 is a dished out portion 17 and whenthe intermediate sole 12 is disposed in abutment with the insole 13these: dished out portions are intended to be disposed in the openings14 it, therefore, being apparent that the members. 15 are arranged ontheintermediate sole "12 in the same'spaced apart relation as existsbetween the openings 14in the insole 13. At the toe portion of theshoe Iprovide a plate member :18 which is arranged so as to be of a configuration substantially similar to the configuration of said toeportion and the dished out portions 17 are formed in this plate member18. The plate member 18 is held in position by projecting elements 16which are also driven into the intermediate sole 12. At the heel portionof the shoe I provide a plate 19 in which the dished out portions 17 areprovided and the projecting elements 16 are also provided on this plate19 as clearly illustrated in Fig. 2. lVhen the insole 13 andintermediate sole 12 are arranged such that the projections created bythe dished out portions 17 are disposed in the openings 14 these twosoles are stitched together in the manner well understood in the art.

Prior to the time the insole and intermediate sole have been secured inposition on the upper and prior to the time they are secured together Iarrange the fastening elements 20 and 21 in position. The fasteningelements 20 are arranged such that the head portions 22 thereof aredisposed in the dished out portions 17 on the anchoring elements 15 andthe plate 18 and such that the head portions 23 on the anchoringelements 21 are disposed in the dished out portions 17 in the plate 19and the shank portions 24 and 25 of the elements 20 and 21 are extendedthrough openings in the intermediate sole l2 and through openings in theouter sole 10 and the outer ply 11, it being understood that the shankportions 25 also extend through the intermediate plies 26 in the heelconstruction.

In the outer sole 10 and the outer ply 11 in alignment with the openingsthrough which the shank portions 2& and 25 extend I provide conicalopenings such as those indicated at 27 in Fig. 4: it being apparent thatthe wider portion of these conical openings is outwardly disposed.Securing elements such as 28 are provided which have conicalperipheries. Oppositely disposed slots 29 are formed in the securingelements 28 and axialiy arranged tapped openings 30 are also provided inthese elements. The outer ends of the shank portions 24 and 25 arethreaded ant. these threaded portions are disposed in the conicalrecesses 27. Therefore, the securing elements 28 are arranged such thatthe threaded end portions of the shank portions may be extended into theopenings 30 in these elements. In order to facilitate the positioning ofthe securing elements 28 I provide a tool such as 31 (Fi 8) whichincludes a handle portion 32 and abifurcated end portion The bifurcatedend portion is arranged such that the prongs thereof will be disposed inthe slots 29 and, therefore, the securing elements 28 may beexpeditiously screwed into position so as to securely fasten the outersole 10 and the outer ply 11 in position. In Fig. 7 I depict a modifiedform of construction for the tool and herein I show a tool 3e having abifurcated end portion 35 substantially similar to the bifurcated endportion 33 and this tool 3 1 is mounted in the body portion 36 of a socalled pocket-knife construction which includes a blade 37. It apparentthat the sole 10 and the outer ply 11 may be expeditiously removed andreplaced by merely unscrewing the securing elements 28 through the useof a tool such as that described.

In Fig. 12 I have depicted a modified form of construction for thesecuring elements which will be particularly adaptable for use on socalled sport shoes and in this instance I have provided on the outersurface of the se curing elements 28 projecting portions or cleats 38. g

It is to be understood that while I have described one arrangement forthe anchoring elements 24- and. 25 and the securing elements 28 it is tobe understood that these parts might be interconnected in differentmanners without departing from the purview of my invention.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into efiect, this is capable ofvariation and modification, without departin from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims.

Having thus described my invention what I claim as new and desire toprotect by Letters Patent is:

1. In a boot and shoe construction. an insole, an intermediate sole,anchoring elements on said intermediate sole, an outer sole havingrecesses therein, means for interconnecting said soles comprisingfastening elements including head portions mounted in the anchoringelements on said intermediate sole, and securing elements disposed inthe recesses in said outer sole and connected to said fasteningelements.

2. In a boot and shoe construction, an insole provided with openings, anintermediate sole, anchoring elements on said intermediate sole havingdished out portions therein projecting into the openings in the insole,an outer sole having recesses therein, means for interconnecting saidsoles comprising fastening elements including shank portions and headportions whereby said head portions may be disposed in said dished outportions and said shank portions may be extended into said recesses insaid outer sole, and anchoring elements mounted in said recesses in saidouter sole and engaging said fastening elements.

3. In a boot and shoe construction, an insole provided with openings, anintermediate sole, anchoring elements having dished outportions thereinprojecting into the openings in the insole and means for attaching saidanchoring elements to said intermediate sole, an outer sole havingsubstantially conical openings therein with the wider portions thereofoutwardly disposed, means for inter connecting said soles includingfastening elements'comprising shankportions and head portions extendedsubstantially at right angles to said shank portions, said shank poretions having the outer ends thereof thread ed, said head portions beingdisposed in said dished out portions and said shank portions beingextended so as to dispose the threaded end portions thereof in saidrecesses in said outer sole, and substantially conical anchoringelements having screw threaded openings therein whereby saidsubstantially conical anchoring elements may be disposed in saidsubstantially conical openings insaid sole with the screw threads onsaid anchoring elements in engagement with the screw threads on saidshank portions.

In testimony whereof I aflix my signature.
